Based on the Ozone Mass calculated in this way, the Gas Flow or the Ozone Concentration
can be defined as setpoint.
Refer to section Control of Required Ozone Mass.
5.4.2.4 Dose Control with Limiter Function
This option involves an additional value for optimizing the ozone generation, e. g. measuring
the ozone content in the Off-Gas, measurement of residual ozone in the process water, or
measurement of the Redox potential in the process water.
When falling below or exceeding a certain limit value, the ozone production is reduced or
increased in pre-defined stages in order to ensure a process optimized ozone production.
Refer to section Limiter Settings.

Correction of the set Dose setpoint. Depending on the ratio setpoint / process
value of the process variables of the Limiter, the set Dose setpoint is
increased or reduced.

The calculation of the Ozone Dose setpoint is carried out downstream the Dose Control, The
Limiter function can only be used with the Dose Control mode, not with the Required Ozone
Mass Control.
Refer to section Dose Control.
